Finding the root of a bandwidth spike with CPanel/Webalizer

Hello all,

Unfortunately, this morning I received a text from one of my users saying that my website ( http://www.seedsoftime.net ) had exceeded its bandwidth and is now unavailable. It was true. I logged into CPanel and used the included tools (Webalizer/Bandwidth/whatever) to find out that the bandwidth suddenly spiked to about this:

March 1 - ~1.8 GB
March 2 - ~7 GB
March 3 (morning only, first 8 hours of the day) ~18 GB

Very odd. And I do have remote image linking blocked.

I looked to the logs to see if any particular IP addresses were consuming large amounts compared to others, and the highest single IP/host was only about 10x higher than what a moderately-active user produced. So there was no huge bandwidth spike from any one hostname.

What else should I look for to try to find the root of this problem?

(Also, this morning I purchased hosting and am switching to a much, much larger host-- Dreamhost-- despite the recent issues they had with payments)
